Alexander began climbing at the age of six. At just ten years old he was climbing 300m multi-pitches with his father. In 2006 Alexander began training with the local bavarian team “Landesstützpunkt Franken” and later with “Bundesstützpunkt Sportklettern” in Erlangen-Nürnberg, where he met his coaches Ludwig “Dicki” Korb and Patrick Matros, who still coach him today.
Alexander’s ascent of Estado Critico in Siurana, Spain in 2013, when he was 19, is the world’s first published 9a onsight.
On the 9th of May 2018, Alexander clipped the chains on his first 9b+ (5.15c) “Perfecto Mundo”, (first ascent, route bolted by Chris Sharma).
In 2007, at the age of 14, Alexander climbed his first 8a (French scale) and in 2009 his first 8c “Drive by Shooting” and in 2011 his first 9a “San ku Kai”. Today Megos spends most of his time training and travelling to world famous crags where he often climbs the hardest routes or opens new routes.
